Answer:

15 unit^2

Step-by-step explanation:

Cut the shape into a square and a triangle, Do 3 x 3 for the square, which equals 9

Now subtract the 7 by 3 to find the length of the side of triangle, which is 4

The formula for triangle's area is 1/2 L x W, so 1/2 of 12 is 6, and 9+6 is 15

first bar: 4(high),21(across)

second bar: 9(high),22(across)

third bar: 12(high),14(across)

Answer:

m2 = 145

m3 = 145

m4 = 35

Step-by-step explanation:

m<1 = m<4 because of vertical angles

m<2 + m<1 = 180

m<2 + 35 = 180

m<2 = 145

m<2 = m<3 because of vertical angles

Answer:

Step-by-step explanation:

180°-35°=145°

vertical angles are congruent so 1 ≅4 and 2≅3

Answer:

f(x)=a(x - h)2 + k

Much like a linear function, k works like b in the slope-intercept formula. Like where add or subtract b would determine where the line crosses, in the linear, k determines the vertex of the parabola. If you're going to go up 2, then you need to add 2.

The h determines the movement horizontally. what you put in h determines if it moves left or right. To adjust this, you need to find the number to make the parentheses equal 0 when x equals -2 (because moving the vertex point to the left means subtraction/negatives):

x - h = 0

-2 - h = 0

-h = 2

h = -2

So the function ends up looking like:

f(x)=a(x - (-2))2 + 2

Subtracting a negative cancels the signs out to make a positive:

f(x)=a(x + 2)2 + 2

Step-by-step explanation:

The translated value of the function is h ( x ) = ( x + 4 )² - 7

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x²

we can obtain the function h(x) by first translating it 4 units to the left, which gives us f(x + 4), and then translating it 7 units down, which gives us f(x + 4) - 7. Therefore, the function h(x) can be written as:

h(x) = f(x + 4) - 7

To write this in vertex form, we need to complete the square. First, we have:

h(x) = f(x + 4) - 7

h(x) = (x + 4)² - 7

This is the vertex form of the equation for h(x). The vertex of the parabola is at the point (-4, -7), which is obtained by setting x + 4 = 0 in the equation above.

The value of the vertex is -7, which is obtained by subtracting 7 from the squared term.

Therefore, the vertex form of the equation for h(x) is:

h ( x ) = ( x + 4 )² - 7

Hence , the transformed function is h ( x ) = ( x + 4 )² - 7

Answer:

I  would say A

Step-by-step explanation:

The price of the pizza and the number of toppings added is  most likely show a positive correlation when graphed on a scatter plot.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The data that will most likely show a positive correlation when graphed on a scatter plot is the price of the pizza and the number of toppings added.

As the number of toppings added to a pizza increases, the price of the pizza is likely to increase as well.

we can expect to see a positive correlation between these two variables when graphed on a scatter plot.

Hence, the price of the pizza and the number of toppings added is  most likely show a positive correlation when graphed on a scatter plot.

Answer:d it’s obviously d brainlyest plz

Step-by-step explanation:

We know that,

[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]

Let's find out the side first. We know that,

[tex]\bigstar \: \boxed{\sf {T.S.A_{(Cube)} = 6\ell^2}} \\ [/tex]

According to the question,

[tex] \longmapsto \sf {54 = 6\ell^2 } [/tex]

[tex] \longmapsto \sf {\dfrac{54}{6} = \ell^2 } [/tex]

[tex] \longmapsto \sf {9 = \ell^2 } [/tex]

[tex] \longmapsto \sf {\sqrt{9} = \ell } [/tex]

[tex] \longmapsto \sf \red{3 \: units = \ell } [/tex]

Now, calculating volume :

[tex]\bigstar \: \boxed{\sf {Volume_{(Cube)} = (\ell)^3}} \\ [/tex]

→ Volume = l × l × l

→ Volume = 3 × 3 × 3

→ Volume = 27

Answer:

8750

Step-by-step explanation:

Since the random sample contained 125 out of 500 people who voted for the dog park that is about 25%. since 25% of 500 is 125. If we scale that up to 25% of 3500 it would be 8750 people.

Answer:

The answer would be 8,750

Step-by-step explanation:

Out of a group of 500 from the 35,000, 125 people wanted a dog park. So find out how many groups of 500 are in 35,000. Which is 70 groups of 500. Since there's 70, you multiply 70 groups by 125
